A

L2-3

29
Q

31
Q

What is the function of the pampiniform plexus?

41
Q

What is the epididymis?

A

Attached to the body of the testis
Stores sperm that is produced from the testis

42
Q

What is the vas deferens?

A

Muscular tube which arises from the tail of the epididymis and transverses the inguinal canal
Enters pelvis by crossing over the external iliac vessels
Joins the duct of the seminal gland to form the ejaculatory duct

43
Q

What are the seminal glands?

A

Paired structures located on either side of the posterior surface of the bladder
Key role in normal functioning semen - alkaline fluid, fructose, prostaglandins and clotting factors

44
Q

What is the prostate gland?

A

Fused to inferior part of the bladder and surrounds prostatic urethra
